Is there a surgery to permanently reduce waist?

If the waist was smaller at one time, the waist can likely be reduced to those same measurements or smaller provided the muscular and fascial integrity has remained the same.  Kenneth Hughes, MD, Board Certified Plastic SurgeonLos Angeles, CA

Thank you for your question. Without photos it is difficult to address your anatomy. I use VASER Hi Def lipo technique to permanently reduce the waist line. This might require some fat grafting to the hips to further accentuate the waist line, especially in a short waisted individual. Of course, maintaining your weight is important, it sounds like this is not an issue with you.See a board certified plastic surgeon experienced in advanced body sculpting techniques for an in person consultation/evaluation. Good luck.

For best results, I recommend a hi definition procedure like VASER liposuction. I use VASER HI DEF with ThermRF and fat grafting to get the most fat removal, skin tightening, contour and definition. This combination will give you the best result for an hour-glass shape. I recommend getting a formal evaluation with a hi definition physique expert. Best, Dr. Emer

Hello thanks for sharing your query. The shape waist or the narrowest portion of abdomen depends on your rib cage and pelvis structure and also on the abdominal muscles. Though people have gone extremes of removing ribs to achieve a narrow waist it is not advised for all. An alternate way to create a narrow waist is the oblique muscle fascia plication and superficial fascia plication. But this will require an abdominoplasty type of incision. Consult a board certified plastic surgeon.

The last anatomic obstruction to horizontal waistline reduction is rib removal. If ever other soft tissue reduction has been done (liposuction and oblique abdominal fascial plication if so indicated), then subtotal rib removals (10,11,12) with latissimus dorsi muscle wedge resection will provide the las definitive effort for waistline shape improvement. 

It is difficult to change someone's skeletal muscular structure.
Very aggressive abdominoplasty with extreme muscle tightening can bring the waist in.
Waist trainers can work but they require an immense amount of pressure for a very long long periods of time.
More than most women are willing to undergo.
People in the past have created body transformations with continuous pressure like neck elongation in African tribes and bound feet in Chinese women.
Stay away from having your ribs cut.
Patients with a substantial amount of subcutaneous fat can create a more hourglass figure by removing fat strategically.
